DETAILED DESCRIPTION

[0051] FIG. 1 shows a system 1 for activating a function or a function test of a medical device according to the disclosure in a schematic diagram. A camera 4 is attached to/in AR glasses (AR device) 2 and comprises a defined field of view 6. The field of view 6 comprises, for example, a dialysis machine 8, as a medical device, with disposables 10, which are attached thereto and which, in this case, are the lines (blood lines, dialysis fluid lines) intended for replacement and a dialyzer of the dialysis machine 8. In addition, at least one CPU is provided which is connected to the camera 4. This CPU can be a stationary, possibly device-specific computing unit or a mobile, AR glasses-specific computing unit, it being possible in the case of a stationary computing unit that the AR glasses only have a data transmission unit. The CPU (not shown) preferably in the dialysis machine 8 and/or on the AR glasses 2 identifies the actual arrangement (actual state) of the disposables 10 and compares it by means of an image analysis algorithm with a desired arrangement (desired state), which is stored in a storage medium of the CPU or which is retrieved via W-LAN. If the algorithm identifies that the disposables 10 are incorrectly/incompletely attached, a correction step in the user's field of view corresponding to the field of view 6 of the camera 4 is overlaid in the AR glasses 2. If the algorithm identifies that the disposables 10 are correctly attached, the CPU emits a command to the dialysis machine 8 to perform a function or function test, preferably by means of W-LAN or wireless technology available under the registered trademark BLUETOOTH® or the like. If the function test is positive, this is displayed on the AR glasses 2. If the function test is negative, a correspondingly required correction step is displayed on the AR glasses 2.

[0052] FIG. 2 shows the method for activating a function/a function test of a device (dialysis machine 8) taking into account the above system 1.

[0053] In step 112, the camera 4 identifies the actual state of the dialysis machine 8. In other words, the camera 4 captures one or more images that display/document the current actual state.

[0054] In step 114, the CPU compares the actual state of the dialysis machine 8 with a desired state of the dialysis machine 8. In other words, the image of the camera 4 from step 112 is compared with a stored image on the CPU and pattern recognition is used to determine whether the actual state corresponds to the desired state. If such a comparison is not possible, for example due to an unsuitable image, step 112 is executed again until an image is obtained that shows the actual state and can be compared with a desired state. This repetition process or the presence of an unsuitable image can be displayed on the AR device e.g. with a preferred message/correction instruction indicating that the viewing angle needs to be changed, for example. If a comparison of the actual state with the desired state is achieved, the next step follows.

[0055] In step 116, the CPU transmits a command for starting a function test to the dialysis machine 8. In other words, once the CPU has positively compared and assessed the actual state with the desired state, a command is issued to the medical device/dialysis machine to perform a function/a function test to check whether the assembly was carried out in a functionally correct manner.

[0056] In step 118, the dialysis machine 8 performs the function or the function test. In other words, a corresponding action is carried out on the dialysis machine 8 in response to the command from the CPU.

[0057] In step 120, the dialysis machine 8 transmits the result of the function test to the CPU or the CPU measures the test result and then graphically displays the result on the AR glasses 2. Here, the result is preferably the pressure/pressure curve that prevails/was induced for test purposes in the disposables/lines.

[0058] FIG. 3 shows the system 1 for activating a function or a function test of a medical device according to the disclosure in a schematic diagram with an augmented reality guide on the basis of FIG. 2. The camera 4 is attached to the AR glasses 2 and comprises the defined field of view 6. The field of view 6 (corresponds to the diagram in FIG. 3) comprises e.g. the dialysis machine 8 (medical device) with the disposables 10 (e.g., fluid lines, tubing, dialyzer, etc.) attached thereto. Windows 122, 124 and 126 are overlaid in the field of view as well as arrows representing instructions for handling (e.g. the straight arrow next to window 122 and the semicircular arrow next to window 124). The first window 122 can contain instructions such as “Pass the tube through the connector”. The second window 124 can contain instructions such as “Insert the blood tube into the blood pump as shown in the video”. The third window 126 at the bottom edge can have a size different from that of one of the other windows, for example be larger, and a video can be shown in this window, for example a YouTube video.

[0059] FIG. 4 shows a schematic diagram of a possible interaction between the AR device, the user, and the CPU. In FIG. 4, the method is divided into the method steps carried out by the AR device (see column 128), the method steps performed by the user (see column 130), and the method steps carried out by the medical device (see column 132).

[0060] In step 134, the AR device or the CPU attached thereto identifies that the task “connecting the disposables” has been identified.

[0061] In step 136, the medical device is informed that the task “connecting the disposables” has been identified.

[0062] In step 138, the medical device prepares for a function test.

[0063] In step 140, the user then installs the lines.

[0064] In step 142, the AR device identifies that the lines have been connected and can additionally or alternatively check for incorrectly connected lines.

[0065] In step 144, the medical device is informed that the disposables have been installed.

[0066] In step 146, the medical device performs a function test of the lines.

[0067] In step 148, the medical device informs the AR device about the positive test or the result.

[0068] In step 150, the result is displayed in the AR device. If the result is negative, the steps from step 142 are repeated.

[0069] If all is well, the next step is displayed in the AR device in step 152.
